种植密度对紫米稻产量形成特性的影响
Effect of Transplanting Density on Yield Formation Characteristics of Purple Rice
摘要
Abstract
‘ Liangtianzi No.1 ’ was used as material to study the influence of transplanting density on the yield formation characteristics of purple rice.The results showed that the whole duration of ‘ Liangtianzi No.1 ’ was 146 d.Its biomass yield was above 10 t/hm2,while its economic yield was only about 3 t/hm2.Transplanting density had a large impact on number of effective panicles,grains per spike,seed setting rate and yield of purple rice variety.In this experiment,planting spacing of 20.0 cm × 20.0 cm gained the highest yield,3.63 t/hm2.Key techniques for high-yielding cultivation of ‘ Liangtianzi No.1 ’ remain to further research.关键词
